ROSA
ROSA turns EPOS data into actionable insights, helping manufacturers and suppliers prioritize stores, deploy field reps efficiently, and capture retail sales opportunities.

Why on-shelf availability (OSA) matters
When a product isn’t on the shelf, 49% of shoppers won’t wait: they’ll buy a competitor’s brand. The consequences? Missed sales opportunities and weakened customer loyalty.
Yet achieving high OSA comes with challenges:
- How do you pinpoint the issues affecting store performance?
- Which locations demand immediate attention?
- What strategies ensure lasting improvements?
How ROSA detects anomalies with EPOS data
The key to solving OSA challenges lies in the data. ROSA scans EPOS data at the store level to find performance anomalies. Instead of sending teams on inefficient store visits, it pinpoints exactly where action is needed.
Common issues ROSA identifies:
- Poor On-Shelf Availability
- Zero sales SKUs
- Underperforming SKUs
- Recurring out-of-stocks
- Underperforming stores


From detection to resolution
Once an issue is detected, it doesn’t stop there. ROSA triggers instant alerts, sending tasks directly to your sales reps or Roamler merchandisers via the Roamler app.
Fixes happen immediately. Our merchandisers work during standard hours, evenings, and weekends to tackle in-store issues when they matter most. Every action feeds back into the system, creating a cycle of continuous improvement.
Examples of in-store tasks include:
- Checking and adjusting shelf placement.
- Verifying facings and correcting discrepancies.
- Ensuring price tags are accurate and clearly displayed.
- Investigating and addressing underperformance drivers.
- Adding stock to shelf
- Correcting Book Stock / Inventory Errors
